Geometric algebra sounds great! I viewed some youtube videos introduce this before. I am curious about some solid issues that can be resolved after introducing geometric algebra into this package. Would you like to share some benefits with me?
Let's say that there's a set of input data that can be represented as a collection of XYZ coordinates, and we're trying to determine a mapping of each input set to some output set. This could be done in geometric algebra in a single layer, if the activation function is "the sandwich product" and the value being estimated is what's known as a motor, a single element in geometric algebra which represents both translation and rotation.
That's obviously a very simple example, and there are other ways to solve that problem, but the point is that many operations that are hard to represent in linear algebra are trivial in geometric algebra.
I support this idea
Geometric Algebra, also known as Clifford Algebra, is a natural mathematical language for geometric applications (as the name would imply).
Although this is certainly a non-trivial addition to the package, there would be tremendous benefits to being able to specify a geometric system, and have a machine learning framework determine the necessary parameters to satisfy the system given the observations.
